Dewalt DCHT820b Cordless Hedge Trimmer Review


Maybe the best feature of Dewalt DCHT820b Cordless Hedge Trimmer that we have found is its ability to precisely cut whatever you’re dealing with. Branches, hedges, shrubs, and other unruly bushes, this hedge trimmer has dual-sided blades with hooks. The unique teeth of this tool allow you to evenly trim your yard.

The Dewalt DCHT820b Cordless Hedge Trimmer has 22-inch blades, which is a good size for heavy-duty tasks. The 2800 stokes per minute provide enough speed to complete your yard tasks fast. The Dewalt DCHT820b Cordless Hedge Trimmer also has dual-action blades, which adds to the efficiency of this tool.


Another factor we like about the Dewalt DCHT820b Cordless Hedge Trimmer is its design. The overall aesthetic is not only well-thought-of when it comes to appearance, but it also adds to the ease of use of the tool. The Dewalt DCHT820b Cordless Hedge Trimmer has an ergonomic design, with a handle location perfectly crafted for the right balance.

When it comes to battery life, the Dewalt DCHT820b Cordless Hedge Trimmer offers decent run-time. Although the lithium-ion battery only provides 20V power, it doesn’t compromise the length of the trimmer’s running time. This tool may not have the strongest motor, but the battery life won’t disappoint. Another good thing about the battery of Dewalt DCHT820b Cordless Hedge Trimmer is it’s compatible with other tools of Dewalt. It could be a huge help if you love this brand, and you have several power tools from them.

The Dewalt DCHT820b Cordless Hedge Trimmer is on the light side of its class. Usually, trimmers are heavy tools, but with this product, the weight won’t be a problem. It’s a compact power tool and though it doesn’t have carburetors, spark plugs, nor air filters, it didn’t compromise efficiency.

For environment-conscious people, we would say the Dewalt DCHT820b Cordless Hedge Trimmer is an excellent choice. It leaves no carbon footprint as it’s battery-operated. It’s one of the main concerns about using hedge trimmers, as older models are gas-powered. There are still many gas-powered models today, which some people prefer because these tools typically provide more power than those that are battery-operated. Thankfully, today’s advanced technology provided us more options to be able to live a comfortable life without hurting the environment.

Now, we talk about the downside. The Dewalt DCHT820b Cordless Hedge Trimmer is probably one of the most affordable models in the market today that still assures efficiency. However, we find it odd that when you purchase this tool, you will only get the unit. The extra batteries and the charger are not included with the unit. It’s a huge deal-breaker for many customers.

Other consumers also report that they didn’t get a safety sheath with the product. However, if you don’t mind these factors, other features like efficiency and weight can override these drawbacks.

On the other hand, it’s definitely easy-to-use with its comfortable handle, ergonomic design, and it’s not complicated to start.

It’s unlike most gas-powered hedge trimmers, which can be complicated to use as you will have to pour gas to the tank and pull the cord before you can use the product. The Dewalt DCHT820b Cordless Hedge Trimmer is just one pull of a trigger away to work.

Light. Weighing only 8.8 pounds, the Dewalt DCHT820b Cordless Hedge Trimmer won’t strain your hands and arms quickly. The weight of tools like this plays an important role in the efficiency and comfort of use. Unlike before, men usually are the only ones using hedge trimmers because of the tool’s weight. Now that we have more and lighter options for machines like this, now women can also handle yard work. No matter what’s your gender, it’s always better to choose a hedge trimmer with lighter weight, as heavier tools can make you feel exhausted faster. Hedge trimmers with less weight are also more convenient to use, as you can carry it anywhere you go.

Cordless. Hedge trimmers with cords limit your movement. It’s a critical feature because these tools are typically used outdoors. It’s probably also the reason why many hedge trimmers before are gas-powered because corded models are not practical nor convenient to use.

That’s why being cordless is one of the highlights of the Dewalt DCHT820b Hedge Trimmer. You can go around your yard and trim as much hedge or shrubs you like to work on without any limitations from having a cord. It will also save you effort, energy, and money as you won’t need to get extension cords to use the product.

Although when it comes to voltage, cordless hedge trimmers may not be the best option that can provide great power. Still, the Dewalt DCHT820b Cordless Hedge Trimmer is a decent tool that can help you do your yard tasks whether it’s for minimal or heavy-duty work.

Precise. Precise cutting is one of the crucial factors to consider when getting a hedge trimmer. Typically, you will have to cut, trim or shape bushes and vegetation around your home or your yard. The Dewalt DCHT820b Cordless Hedge Trimmer is a product you can count on when it comes to evenly trimming plants.
